Matthew 19:27

Behold we have left all! What confidence this in Peter! He ad been but a fisherman, always poor, living by his industry, and gaining his bread by the sweat of his brow; yet with great confidence he says, we have left all. (St. Jerome) --- For, we are not to consider what he left, but the will with which he left his all. He leaves a great deal, who reserves nothing for himself. It is a great matter to quit all, though the things we leave be very inconsiderable in themselves. Do we not observe with how great affection we love what we already have, and how earnestly we search after what we have not? It is on this account that St. Peter, and his brother, St. Andrew, left much, because they denied themselves even the desire and inclination of possessing any thing. (St. Gregory, on S. Mat. hom. v.) --- Though I have not been rich, I shall not, on that account, receive a less reward; for, the apostles, who have done the same thing with me, were no richer than myself. He therefore leaves all the world, who leaves all he has, and the desire of ever having more. (St. Augustine, ep. lxxxix. ad. Hilar.)
